 Maggot. — New Jersey Agric. Expt. Sta., New Brunswick, Circ. 

 138, February 1922, 4 pp., 2 figs. [Received 10th October 1922.] 



Details are given of the tests carried out in New Jersey with a 

 view to ascertaining the relative efficiency of commercial tar paper 

 pads, tar and sand mixture, and mercury bichloride in the control of 

 the cabbage maggot [Phorbia brassicae, Bch.] [cf. R.A.E., A, ix, 372]. 

 Mercury bichloride is recommended to commercial growers of early 

 cabbage and cauliflowers in New Jersey, as it is the most easily applied, 

 most economical and most efficient of these substances. During these 

 experiments the first application was made when the plants were set 

 out in the field, the second 8-10 da^'s later.

The outbreaks of Brachartona catoxaiitha on coconuts recorded in 

 recent reports [R.A.E., A, x, 33, 202] have been controUed by the 

 action of insect and fungous parasites. Rice pests, besides stem- 

 borers, included Nymphula depunctalis, damaging nursery plants, the 

 leaf-eating caterpillars of Parnara mathias and Melanitis isniene, the 

 former of which were largely controlled by a Hymenopterous parasite, 

 and scattered groups of locusts, which in some localities did serious 

 damage. The nurseries were swept with hand nets to catch the nymphs, 

 while the adults were taken in large numbers when resting on tree 

 stumps at night. Certain species of grasshoppers are always present 

 on rice ; the biology of these is being studied. .Gryllotalpa sp. (mole 

 cricket) was injurious in dry weather, but disappeared with the advent 

 of rains. The rice bug, Leptocorisa varicornis, reappeared in some 

 localities ; lamps at night and poison bait by day were used against it, 

 but the damage was not serious. Another bug, Podops coarctata, 

 became a pest when the rice area was dry at the wrong time, but 

 disappeared with moister weather. With a good water supply there 

 is seldom danger froni this pest.

 Year 1921.— 5/ra//s Setllcmenls [Singapore], 6th July 1922, 5 pp. 



The pests recorded during 1921 are Protoccrius colossus, Rhynchophonis 

 ferrugineus and Oryctes rhinoceros on various pahns, the attacks of 

 which were reduced by handpicking, a larva, probably of Zeuzera sp., 

 in branches of wild Litsea and avocado pears, and Papilio polytes on 

 Citrus.

Tn view of reports that infestation by the coffee-berry borer 

 [Stephanoderes hampei] had decreased in West Java owing to fungus 

 infection [R.A.E., A, x, 507], it was thought advisable to test their 

 accuracy and to ascertain what conditions favoured the fungus, 

 and whether a natural decrease of the infestation resulted. The
